85 IROC will not start!!! - Third Generation F-Body Message Boards

Have an 85 IROC-Z 305 TPI just replaced the distributor, pick-up, coil, module, cap and rotor. All wiring is correct. Fuel pump works and has correct pressure at the shrader valve on the fuel rail. The cold Start Injector is working as the motor will start and run for about 2 seconds. The timing is set correct and is apparent when using the starter and timing light it shows at 4 degrees BTDC. Any Suggestions? Im thinking that the other injectors are not pulsing since once the cold start injector cuts out the engine quits. Fuses are good and the computer and engine were working prior to distributor replacement. Suggestions??? Thanx

Set the iac and tps correctly...........directions are in the technicl articles at the very beggining of the forum.........do that, and go from there..........check for vac leaks as well.

check and see if wires to oil senders are all on, the two wire plug runs fuel pump after startup.
